REGULATION. TECHNOLOGY. POLICY.
WE HAVE AN EYE ON THE FUTURE.

USEPA is in the midst of developing a
handful of new national regulations
for inorganics. Some inorganics are
under consideration for a new standard
while others would be addressed by
revising an existing standard. For a new
contaminant, the 1996 Safe Drinking Water
Act (SDWA) Amendments require EPA to
use a four-step process for developing a
national drinking water regulation:
• On a five-year cycle, EPA publishes a
Contaminant Candidate List (CCL) for
contaminants that could be considered
for a national regulation.
• Also on a five-year cycle, EPA is required
to make decisions, known as regulatory
determinations, on at least five
contaminants. Besides a binary yes/no
on regulating or not regulating a specific
contaminant, EPA can make other
decisions such as issuing guidance or a
health advisory, or that more research is
needed for a specific contaminant.
• If EPA decides to regulate a specific
contaminant, then it has 24 months to
publish the propose regulation.
• The final regulation has to be published
36 months after the above decision.
EPA is also required by SDWA to review
all existing regulations every six years to
take into account any new health effects or
occurrence data, new analytical methods
and any new treatment research. The sixyear
review is the process through which an
existing standard is revised.
2013 Regulatory Actions
This year EPA will propose three regulatory
actions for inorganics, with the first
being the “preliminary third regulatory
determination” in the summer. Based
on the information presented at a stakeholder
meeting in Washington, DC in June
2011, positive determinations are likely
for nitrosamines, chlorate and strontium,
The Regulatory Horizon
By J. Alan Roberson, P.E., AWWA Director of Federal Regulations
CA-NV AWWA hosted a twoday
symposium on inorganic
contaminants in Sacramento
on February 5-6, 2013.The
following article is based on Alan
Roberson’s opening keynote
from the symposium and takes
a look at what AWWA sees on
the regulatory horizon.
